[washerbroken2]

My Whirlpool top-loader LSC8244EQ0 agitator stopped working last week. I took it apart and found the motor coupler in pieces. I ordered one and replaced it last night. This morning my wife washed a load. For the first ten minutes everything seems fine, then she reported burning smell and shut off the washer.

I took it apart and found a rubber belt/gasket loose on a round housing below the tub, and above the drive gear housing (?).

See the attached pictures for the loose belt/gasket.

Questions:
1) What is this part?
2) Is it difficult to fix?

Thank you so much.
